Answer:
The amount spent on the refrigerator is $ 800 .
Step-by-step explanation:
Given as :
The amount spent on television = $ 1600
Le The total amount in the account = $ A
so, The amount left in account after spent on television = $ A - $ 1600
The amount spent on refrigerator = × ( A - 1600 )
The amount left in his saving account = × A
Now, According to question
A - ( 1600 + × ( A - 1600 ) ) =
× A
Or, A - × A = 1600 +
× ( A - 1600 )
Or, × A = 1600 +
× A -
× 1600
or, × A -
× A = 1600 - 640
Or, × A = 960
or, × A = 960
∴ A =
I.e A = 3600
So, The amount in the saving account is $3600
∵ , The amount spent on refrigerator = × ( 3600 - 1600 )
Or, The amount spent on refrigerator = × 2000
I.e The amount spent on refrigerator = $ 800
Hence The amount spent on the refrigerator is $ 800 . Answer
Answer:
Step-by-step explanation:
Red:black = 1:1
Red cards = x
Black cards =x
x + x = 48
2x = 48
x = 48/2
x = 24
No. of red cards = 24
No of black cards = 24
Now 8 red cards are removed
So, No. of red cards = 24 - 8 =16
Red: Black = 16:24
Red: Black = 2:3
